Vesicular breathing - physiology and pathology

Due to excess weight, the chest wall becomes thickened. Surface weakened vesicular breathing occurs as a result of the stressed state of small particles of the lungs (alveoli) because of their uneven distribution.

Pathology of vesicular breathing

The causes of a pathological disturbance of natural respiratory noise may be the following: insufficiently enlarged lungs during inspiration; Any obstacle for listening to breathing noise; Difficulty in the passage of air masses in the lungs.

Weakened vesicular breathing

Bronchial, guttural, tracheal narrowing leads to a hindered entry of air masses into the lungs. The cause may be a postoperative scar, and a blockage of foreign objects, and tumor growths. With a decrease in the laryngeal and tracheal organs, weakened vesicular breathing will be audible throughout the thorax. The narrowing of the bronchi leads to the fact that the weakening of the breath is heard only in the places of constriction. Corking with tumor build-ups or foreign bodies is characterized by a complete lack of listening.

Other diseases leading to a weakening of vesicular breathing:

1. Emphysema. With the loss of flexibility of lung tissue, there is practically no expansion of the pulmonary system during inspiration.

2. Focal pneumonia. In the lungs, the vesicular breathing is weakened by decreasing the alveolar wall tension.

Types of breathing

- Accumulation in the pleura of liquid or air fillings also leads to poor listening of the breath.

- With increased temperature, physical exertion, vesicular breathing intensifies (intensified).

- Sharp breath with signs of roughness is called hard. In this case, it can take both normal flow and weakened.

- Succeded (intermittent) breathing occurs with small pauses. The cause of this is an uneven muscle contraction. It indicates a narrowing of the small bronchus due to inflammatory processes. Breath intermittent due to the passage of air into the respiratory system in several portions.

- The pathology of bronchial respiration is present when the lungs contain small, compacted areas containing air masses and come into contact with the bronchi. Such seals occur with a heart attack, pleurisy, pneumothorax. Tuberculosis, bronchiectasis, as well as abscesses contribute to the formation of the cavity in the structure of the lungs.

- Mixed type. Vesicular breathing when inhaled and bronchial when exhaled. Pathology is observed in the case of alternation of compressed and normal areas of the lungs. Such symptoms are inherent in the following diseases: tuberculosis, pleural exudates and pneumonia.

Bronchial respiration

When bronchial breathing in the bronchial region should be complete patency. Due to dense sections in the lungs, breathing becomes intense. Loud arises from the disease of croupous pneumonia. The metallic form of breathing (with ringing sounds) is observed with an open pneumothorax.
